My invention is in a hinge suitable for a casement sash and in a casement sash mounting, the constructlon being partlcularly adapted for casement sashes opening inwardly.

An object of my invention is a casement sash construction with a special hinge in which the sash may open inwardly and in the closed position form a water-tight joint with the sill and in the opening position the sash is shifted to clear the elements forming the water-tight closure.

An object of my invention in its simple aspect is the construction of a window or the a like casement sash in which the sash may be lifted slightly, the hinges allowing a sliding movement whereby the sash may clear the inner-part of the molding of the sill and thereby be raised above the elements of the sill, forming a water-tight closure with the sash. And in this feature of my invention the sash may be completely opened or left at any intermediate position, the weight of the sash holding it in the desired position by resting on the inner molding of the sill.

Another object of my invention is the use of a special hinge in connection with a casement sash by which the sash when in the closed position may be elevated slightly to clear the rabbet formed in the sill to raise the lower rail of the sash above the inner molding of the sill, and thereby allowing opening inwardly of the sash, the lower rail havinga free clearance over the inner molding of the sill.

A further object of my invention is the Serial No. 259,775.

the like whether in its lowermost or its uppermost position. In this connection a further object of my invention is balancing the latch so that its upper end normally tends by the action of gravity to fit between the 50 central knuckle and the upper knuckle of the sliding leaf when the sash is raised, thus effecting an automatic latching or locking of the sash when in its elevated position.

A detailed objectin this last construction 55 is to operate the hinge by means of the cam, the cam being manually operated.

My invention will be more readily understood from the following description and drawings, in which:

Fig. 12 is an elevation of one of the leaves of the hinge of Figs. 9, 10 and 11, illustrating the stationar Y leaf having the latch pivotally mounted thereon.

Fig. 13 is an elevation of the sliding leaf of the hinge of Figs. 9, 10 and 11.

The general characteristics of my type of casement sash hinge are as follows: I employ a sill 11 having a window stool 12 on the inside of the window with a rabbet 13 between the outside part of the sill and the stool. The sill is mounted in any suitable type of frame and this frame hi S cross rail 14 at the top with a rabbeted section 15 cut out therefrom. In front of this rail I utilize a closure stop 16 secured to the top board 17 of the window frame 18.

The sash, designated generally by the numeral 19, has a lower rail 20 which in the closed position of the window is adapted to rgst I the sill 11 in the rabbet 13 This sash his the ordinary stiles 21 on each side and has a cross rail 22 at the top with a rabbet 23 out therein. The rabbeted rail 22 at the. is adapted to interfit With the rabraiil 1,4 of the window frame and on n e sash have a cover strip 24 closing in the mbba of the. rail 14.

The hinges, designated generally by the numeral 25, have a stationary leaf 26 secured to, the window frame and a movable leaf 27 secured to the. The stationary leaf is illustrated as havi a single central knuckle 2% an the. moving af as having upper and lower (nuckles 29. These. hubs are so posii ned that there is a clearance space 30 between the central knuckle 28 of one of the leaves and either of the knuckles 2,9 of the other leaf. It is manifest, however, that time? leaves may be reversed if desired. A pint e 31 having a threaded nut 32 on the top is secured in the knuckles of the. leaves, th .completine the hinges.

he device for raising and lowering the 53.511 in the construction. of Figs. 1 through 6 is as follows:

The pintle. 31 of the lower hinge has a downwardly extending rod 31. This rod is preferably formed integral with the pintle 3,1 and has a collar molding 33 thereon enng lower knuckle 29 of the. leaf 27.

us rod extends downwardly through a hole 34 in the window stool 12, and the lower end extends downwardly through an aperture 35 in a cam casing 36, this casing being secured to, the apron 37 of the window frame. The lower end of the rod 31 has a. reduced neck 'llhebottom surface 39 forms a rubbing surface as hereunder indicated.

A cam shaft 40 is journaled in the cam 055i Y 36 and; has a cam 41 mounted thereon. his cam has what is termed a fiat or riding pontipn 42concentric to the shaft and relatively closethereto; also a fiat or riding 6. portion 43 concentric to the shaft, there be.-

ing a gradually spiraled surface 44 connecting the surfaces 42 and 43. A stop lug 45 is positioned on the extreme outside of the cam and there are a pair of prongs 46 which are adapted to extend on each side of the reduced neck 38, forming a lock as hereunder mentioned. The cam shaft is operated by a handle 47.

When the sash is in the lowermost position as shown in Figs. 1 and 2, the bearing end 39 of the rod 32 rests on the portion 42 of the cam and the prongs 46 extending on opposite sides of the reduced neck 38 prevent this rod from having any upward movement, thus locking the hinge and hence the sash in its closed position (note Fig. 6). When the handle is turned in the proper direction, the rod 32 is lifted on the lower end thereof, riding on the spiral surface 44 of the cam until the stop lugs 45 are engaged by the lower end of this. rod. This lifts the moving leaf of the lower. hinge and hence raises the sash into the positions shown in Figs. 3, 4 and 5, so. that the lower edge of the rail 20, clears the upper surface of the window stool 12. The sash. may then be opened, swinging on the hinges, and in the position illustrated the sash may be swung completely open, as shown in Figs. 4 a d If it is desired to open the sash only part way, it is desirable to have a wear plate 48 fitted on top of the. window stool l2 and having an aperture therethrough for the rod 32, so that by reversal of the cam the sash may be lowered to rest on, this. wear plate and thus be positioned at any desired angle. of open. 111g.

In the construction illustrated in Figs. 8 and 9, I preferably use a somewhat differenttype of hinge. In this case what may betermed the moving leaf 50 of the hinge is illustrated as. having upper and lower knuckles. 51 with the usual apertures there.- through and the fixed leaf 52 is, illustrated as havinga single central knuckle The leaf 52 has a rocking latch 54 which is illustrated as an arcuate plate 55 mounted on a pivot 56of the leaf 52; and this has. a pair of locking dogs 57 formed preferably of flanges bent at right angles to the. plate 55. It will be noted that these flanges are not in alignment, but inclined towards each. other, as illustrated in. Fig. 12. The upper hinge issimilar to the lower hinge except that it does not have the rocking latch 54. The hinges are provided with the usual pintl'es 58, these being. illustrated as having screwthreaded nuts 59. thereon.

The rocking latch 54 is sobalanced on the pivot 56 so that the upper dog 57 normally inclines through the action of gravit towards. the. pintle. Thus when the sliding leaf is raised'the upper dog slips between the upper knuckle 51 of the movable leaf and the knuckle 53: of the fixedi leaf.

The sash is illustrated as having lifting handles and a lower rail adapted to fit on a sill in a rabbet, and have the upper raii fitting in a rabbet in the upper rail of the window frame in a manner similar to the construction of Figs. 1, 2 and 3.

The manner of operation and functioning of my sash and hinge of Figs. 7 and 8 is substantially as follows:

The leaf 50 designated as the moving leaf is secured to the stile of the sash, and the leaf 52 of the hinge designated as the stationary leaf is secured to the jamb of the window. When the sash is in its lowermost position the rocking latch 54 may be manually shifted so that the lower dog 57 engages between the lower knuckle 51 of the leaf 50 and the knuckle 53 of the leaf 52, as shown in Fig. 7. This locks the window so that it can not be raised from the outside or without manually disengaging the rocking latch. However, as above mentioned, this latch is so balanced on the pivot 56, the dogs 57 being heavier than the back portion of the latch, so that the upper dog normally inclines towards the pintle; therefore, when the sash is raised the upper dog 57 automatically slips between the fixed knuckle 53 and the upper hub 51 of the mo'v able leaf thereby holding the sash in its up, permost position. This action does not require any manual operation of the rocking latch to hold the sash elevated but it does require manual operation to lock the sash in its lowermost position. When the sash is elevated it may swing over the window sill.

From the above construction of sash and hinge it will be seen that I have developed an inwardly opening casement sash which is rain and wind-proof as to the lower rail, when the sash is closed, 011 account of such rail fitting in the rabbet l3 and the rain will therefore drip ofl the sill. The sash is also wind and Weather proof at the upper rail, on account of the stops 16 and overlapping strip 24 covering in the rabbeted sections 15 and 23 of the rails 14: and 22, respectively. It is to be noted, however, that these rabbets may be made deep cut so that the space and covering strip may be dispensed with.

The type of hinge used is also of a character which, in the construction illustrated in Figs. 4, 5 and 6, automatically locks a sash in its closed position and by turning the cam elevates the sash so that it may be opened and held in any position; and in the construction of hinge shown in Figs. 7 through 13, the hinge and sash may be locked in its closed position or in its open position. By my construction it is not necessary to make hinges in rights and lefts as they can all be made of the same design and merely turning the hinge upside down causes it to function for either the left or the right hand side of the sash.

Various changes may be made in the principles of my invention without departing fromthe spirit thereof, as set forthin the description, drawings and claims;

I claim: V r 1 a 1. A casement sash hinge comprising in combination a first leaf and a second leaf each having knuckles with a pintle therethrough, the knuckles being arranged for relative sliding movement of their leaves on the pintle relative to each other, a rocking latch pivotally mounted on one of the leaves, such latch being adapted to interengage between the knuckles of the two leaves and to hold such leaves in a plurality of positions.

2. A casement sash hinge, as claimed in claim 1, the rocking latch having locking dogs at each end adapted to fit between the knuckles of the two leaves and hold same spaced apart in two different positions of their movement.

3. A hinge comprising in combination a stationary and a slidable leaf, a moving latch member, said latch member being shiftable by gravity to hold the movable leaf in an upper position relative to the stationary leaf,

4. A hinge having a stationary and a slid able leaf connected by a pintle, a moving latch mounted on the stationary leaf and adapted to shift by gravity when the moving leaf is elevated to engage the moving leaf and hold same in an upper position of its sliding movement.

5. A hinge having a stationary leaf and a slidable leaf, a latch pivotally mounted on the stationary leaf and adapted to shift by grav ity to engage the movable leaf when lifted upwardly relative to the stationary leaf and to hold the movable leaf in such position.

7. A hinge as claimed in claim 6, the rocking latch having a second locking dog positioned symmetrical to the pivot in relation to the first locking dog whereby the second locking dog may be manually operated to engage between the central knuckle and the lower knuckle of the movable leaf when the movable leaf is in its lowermost position, and in which the hinge may be inverted to connect to an opposite side of a sash.

8. A hinge comprising in combination a pair of leaves each having knuckles connected by a pintle and said leaves being slidable relatively to each other on the pintle, a look ing dog pivotally mounted 'on one of the leaves on a pivot at right angles to the pintle, and means on said dog to hold the leaves in a plurality of adjusted positions.
